looking for a motor controller that will not break the bank..
i am looking for a 2ch analog motor controller. seen some but they were over $70.00
i am wanting to build me a small PTZ mount for a camera to use on my plane.
i'll be using small modified servos.
i have the joystick, it is 5Kohms 2 axis the current is very small not even 2amps per motor.
and it will operate off of 12v or less.

You want the camera to spin around a complete 360 degrees.
Tilt up or down, and control the zoom, and focus.

For the 360 degree, you could use a simple Toggle\Rocker switch.
Forward - OFF - Reverse.
Same for the other functions.
Then put stop/shut off switches at the end of travel of the, spin, tilt, Zoom, and focus mech.
So you don't strip out the gears when it reaches the end.

i do not want to use switches, i want variable speed using a joystick..
center position is stop..any direction is moving in that direction, but variable speed,
full swing = full speed, partial movement = slow.
i was looking at something like this, but too cheaper, i only need 1-2 amp ability as
it will be driving very small motors such as in a R/C servo. i'll be using 12v.
can be lower as a regulator is not a problem

I think that the $60 for a unit that is similar to this is a good price.
I've seen others that are in the $100 to as high as the $800 dollar range.
But they can control multiple cameras on a CCTV system.

Yeah, I know.
Building it is half the fun.
Only you may find that building a custom controller may cost more than the one you can get for $60.
